CVE-2026-4244

The Post Duplicator plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the `duplicate_post()` function in all versions up to, and including, 3.0.11. This is due to the function not verifying that the user has `edit_others_posts` capability before accepting a `selectedAuthorId` parameter via the `duplicate-post` REST endpoint. This makes it possible for authenticated attackers, with Contributor-level access and above, to create duplicated posts attributed to any user, including administrators.

Summary		(es) El plugin Post Duplicator para WordPress es vulnerable a la modificación no autorizada de datos debido a una falta de verificación de capacidad en la función 'duplicate_post()' en todas las versiones hasta la 3.0.11, inclusive. Esto se debe a que la función no verifica que el usuario tenga la capacidad 'edit_others_posts' antes de aceptar un parámetro 'selectedAuthorId' a través del endpoint REST 'duplicate-post'. Esto hace posible que atacantes autenticados, con acceso de nivel Colaborador o superior, creen publicaciones duplicadas atribuidas a cualquier usuario, incluidos los administradores.
